Explanation of Terms Used in These Regulations
1.0.1 These Regulations are formulated to unify the depth of preparation of design documents for the general layout and transportation construction drawings of chemical plants, ensure design quality, improve design efficiency, and meet the requirements of design, construction, production and archiving. 1.0.2 These regulations apply to the design of general layout and transportation construction drawings for newly built, expanded and renovated large and medium-sized chemical plants. Small factories and off-site projects can appropriately simplify the design content and merge the design drawings based on the specific conditions of the project, on the basis of meeting the design, construction, production requirements and maintaining the integrity of the design. 1.0.3, in addition to complying with these regulations, the preparation of the general layout and transportation construction drawing design documents shall also comply with the provisions of the current national design specifications and drawing standards.
1.0.4 In addition to complying with these regulations, the construction drawing design of factory railway dedicated lines and road projects shall comply with the provisions of the current national design standards and specifications for railways and roads (highways). 1.0.5 The construction drawing design generally consists of drawings, design instructions, and tables. Among them, the railway longitudinal section and railway roadbed cross-section can be drawn according to the needs of the project. Drawings

Drawing layout
Drawing layout should be neat, balanced, beautiful and easy to read. Tables, legends and instructions should be placed on the right side of the drawing. 2.3.1
side or bottom, the compass or wind rose diagram should be arranged on the upper right side of the drawing, and the layout of the view surface should determine, 2.3.2 The orientation of the drawing should be north at the top and south at the bottom, and there can be a deflection angle to avoid arranging the north point downward. 2.4 Coordinate marking
2.4.1 Construction drawing design generally draws a coordinate grid, that is, the construction coordinate grid or the measurement coordinate grid. When drawing two coordinate grids at the same time, the measurement coordinate grid is represented by a crosshair, and the construction coordinate grid is drawn as a through line; when only one coordinate grid is drawn, both are drawn as through lines. 2.4.2 When the construction coordinate system is used in the general layout drawing, the conversion formula with the measurement coordinate system should be indicated in the drawing description, the X-axis of the measurement coordinate network and the A-axis of the construction coordinate network should be indicated on the wind rose diagram, and the intersection angle of the two coordinate axes should be indicated. 2.4.3 When different coordinate systems are used in the design of the engineering inside and outside the factory, the coordinate values of the two different coordinate systems should be indicated at the demarcation point at the same time.
4.4 In the expansion and reconstruction projects, if it is impossible to mark the coordinates, relative dimensions can be used for positioning. 2.5 Commonly used symbols
